Noun
(physics) The length of a single cycle of a wave, as measured by the distance between one peak or trough of a wave and the next; it is often designated in physics as λ, and corresponds to the velocity of the wave divided by its frequency.
(figuratively) A person's attitude and way of thinking as compared to another person's.
I think you and I are on a different wavelength.
Perhaps when distant people on other planets pick up some wavelength of ours all they hear is a continuous scream. Iris Murdoch
For as long as one has no further point of reference, apart from the position of the maximum, the wavelength thus remains uncertain by an integral factor. Max von Laue
Know that your work speaks only to those on the same wavelength as you. Jean Cocteau
Every weirdo in the world is on my wavelength. Thomas Pynchon
We should note that this latter type of shift was successfully amplified to a considerable extent by Russian physicists using the intense light of a ruby laser whose wavelength is close to that of a transition of the potassium atom. Alfred Kastler
In general, the objects in the universe that are very high-energy objects, or the processes that are high-energy processes, will radiate more in the short wavelength range towards the gamma rays or the x-rays. Claude Nicollier
